TxDemo uses 99% of CPU while idle

[ttsou]

When the thread is "stopped," the main loop spins uncontrollably - which is not cool. Among other things, this may cause the ossie-demo waveform to become dysfunctional.

This is kind of curious. I suspect someone made a bad decision when they copied/created the files for 0.7....

This is the oldest version I found of TxDemo?:

http://ossie.wireless.vt.edu/trac/browser/waveforms/ossie_demo/trunk/ossie_demo/TxDemo/TxDemo.cpp?rev=932

does not have this problem. You can get the fix from this code. The code in the components directory is also OK.

I knew this problem sounded familiar. I apologize for leaving this in the email list to get lost, instead of creating a ticket when I first noticed the problem:

In case that link is broken, the email is dated 10 OCT 2008. I can easily be found in the ossie-discuss archive.

Moved the processing thread creation to the start() method. The processing thread is terminated when stop() is called. The fix, included in rev 8583, was tested with version 0.6.2.

That's r8583.

I reviewed r8583 and it looks like if you start, stop, and re-start the waveform, you create a new thread each time you call start, and do not free the old thread. This is probably not a good thing :)

I've spoken with Carlos and confirmed that this issue has been resolved.
